WALTER E. GASKILL, OF PRINCETON, NEW JERSEY, ASSIGNOR TO MERGENTHALER LINOTYPE COMPANY, A CORPORATION OF NEW YORK.

TYPOGRAPHICAL MACHINE.

Application filed February 23, 1915.

0 all whom it may concern Be it known that I, WALTER E. GASKILL, a citizen of the United States, residing at Princeton, in the county of Mercer and State of New Jersey, have invented certain new and useful Improvements in Typographical Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to typographical composing machines, such as linotype machines of the general organization represented in Letters Patent of the United States, No. 426,532, to O. Mergenthaler, wherein circulating matrices are released from a magazine or magazines in the order in which their characters are to appear in print and then assembled in line, the composed line transferred to the face of a mold, the mold filled with molten metal to form a slug orlinotype against the matrices which produce the type characters thereon, and the matrices thereafter elevated and re- .turned through a distributing mechanism to the magazine or magazines from which.

they started. These machines are frequently equipped with a so-called font-distinguisher, which is located in advance of the distributing mechanism and serves to prevent the delivery thereto of matrices of improper font, that is. matrices of a font different from that contained in the particular magazine in use. Ordinarily, the matrices are formed in their lower ends with notches which are differently positioned in the respective fonts, so that only those of a certain font or those having notches in a given location can pass the font-distinguisher. while those of other forms or fonts are arrested thereby.-

' Heretofore in practice, the various fonts of matrices have been distinguished from each other merely in respect to size or what is technically known as point, so that if two or more fonts of matrices were of different style or face but of the same point. it would be possible for them to pass the fontdistinguisher and be. distributed into the same magazine. thereby resulting in a n1ixture of faces and with substantially the same annoyanee and objections as are present in eonneetion with a mixture of sizes.

It is the objeet of my present invention to prevent this liability. and to that end 1 cmploy serel'al font-distingnishers which serve not only to prevent the delivery to the distributing lHWllflHlHlH ol matrices of improper Specification of Letters Patent.

proper style or face.

In the accompanying drawings, I have shown my improvement in preferred form and by way of example and as applied to a linotype machine of the usual construction, but obviously it is capable of broader application, and may be embodied in other forms and applied to other styles of typographical machines, such for instance as type setters, and the like, and still be comprised within the spirit of my invention. Generally speaking, I desire it to be understood that I do not limit myself to any specific form or embodiment, except in so far as such limitations are specified in the claims.

Referring to the drawings: Figure 1 is a front view of a portion of a linotype machine having my invention applied thereto Fig. 2 is a section on the line 2-2 of Fig. 1; Fig. 3 is a section on the line 33 of Fig. 1; Fig. 4 is a section on theline 44 of Fig. 1; and Figs. 5, 6 and 7 are diagrammatic views showing the manner in which matrices of various fonts are distinguished from each other in form.

In the accompanying drawings, I have shown my invention as embodied in a machine equipped with a plurality of magazines, and of the class illustrated in United States Letters Patent No. 1,109,872, to John R. Rogers. In the present instance, only two magazines A A are shown, although of course a greater number could be employed. These magazines are mounted in the shift frame A, which can be moved up and down to bring one or another of the magazines into operative relation to the channel entrance B, into which the matrices are delivered by the distributing mechanism C. Located in advance of the distributing mechanism is the distributer box D, through which the matrices are transferred by the pusher E, the matrices being delivered there from, one at a time, to the distributing mechanism by the lifting finger F, all in the usual way.

According to my present invention, I provide each matrix with a point-distinguishing and two face-distinguishing notches X and X respectively. The notch X is formed in one of the vertical edges of the matrix and is located in difierent vertical positions in fonts of different point. For instance, Fig. I shows diagrammatically size or point, but also of matrices of imeight different positions of the notch X for as many different fonts which vary as to point. The face-distinguishing notch X is formed in the same edge of the matrix and varies in depth according to a given unit in fonts differing as to face. For instance, in Fig. 5 nine different depths of notch areindicated for as many different fonts of unlike face. In order to distinguish a still greater number of fonts, this notch X may also be located in different vertical positions along the edge of the matrix. For example, Fig. 6 indicates eight different vertical positions for the notch, in each of which positions the notch may also vary as to depth. It follows, therefore, that the vertical position of the notch X will be the same for a group of nine difi'erent fonts, and that its varying depths will serve to distinguish these fonts from one another in the group. The other face-distinguishing notch X is formed in the bottom of the matrix and is located in different horizontal positions in fonts of unlike face, Fig. 5 showing nine different positions of the notch. It is to be observed at this time that the notch X bears a special relation to the notch X, the depth of the latter controlling the location of the former. In other Words, any variation in the depth of the notch X will be accompanied by a corresponding difference in location of the notch X The purpose of this will later be pointed out.

To cooperate with the matrices of the special forms above noted, I provide three font-distinguishers 00 w, and :0 These may be located in any convenient part of the machine, but I prefer to mount them in the distributer box D. The distinguisher .70 is associated with the point-distinguishing notch X and is adjustable vertically to correspond to the different'locations of the notch in different fonts. The distinguisher m is associated with the face-distinguishing notch X and is arranged so as to be adjustable vertically and horizontally to correspond both to the different positions and the varying depths of the notch in the different fonts. The distinguisher m is associated with the facedistinguishing notch X and is adjustable laterally to correspond to the different locations of the notch.

The distinguisher x is intended to supplement the'distinguisher .10 as the latter is inadequate in certain conditions. For instance, if the distinguisher aa be set in position to correspond to a notch X of any given depth, then matrices having a greater depthof notch would be allowed to pass the distinguisher and be distributed into an improper magazine. The employment of the distinguisher m avoids this liability, as the notch X of the matrices must also register with the distinguisher m before they can pass thereby. In this connection, it will be remembered that the position of the notch X is dependent upon the depth of the notch X so that it will have as many different positions as the notch X has different depths. It follows, therefore, that even if the depth of a notch X were such as to allow an improper matrix to pass the distinguisher m, the position of the notch X would not permit it to pass the distinguisher w.

The adjustments of the several font-distinguishers may be effected in any desired manner-manually or otherwise. In the present instance, I have shown means for effecting their adjustments automatically, these means being controlled in their action by the movement of the magazines, in such manner that when any selected magazine is brought into operative position, the several font-distinguishers will be properly adjusted to correspond to the particular style and size of the matrices therein contained. Referring to Fig. 3, it will be noted that the point-distinguisher a." is attached to the end of a small plunger G, which is movable vertically within a cylindrical casing G1 attached to the side of thedistributer box, a spring (I being interposed between the casing and plunger and tending normally to push the latter downward to its lowermost position. The downward movement of the plunger G is resisted or controlled by an arm Gr connected to one end of a transverse rock shaft Gr mounted in suitable hearings on the framework. the opposite end of the rock shaft (Fig. 1) being provided with a crank arm G which is connected to an upright lever G. Similarly (Fig. 4) the face-distinguisher w is attached to a plunger H movable vertically within a casing H, a spring H being interposed between the casing and plunger and tending normally to push the latter downward to its lowermost position. This downward movement of the plunger H is resisted or controlled by an'arm H connected to one end of a rock shaft H journaled in suitable bearings in the framework and provided at its outer end (Figs. 1 and 2-) with a crank arm H which is connected to a second upright lever H In order that the distinguisher as may also be adjusted laterally, to vary its extent of projection into the distributer box to correspond to the varying depths of the notch X the casing H is slidably mounted upon two rods H projecting laterally from the side of the distributer box and passing through openings in the casing.

The distinguisher m is carried by a stud I adjustably mounted in the under side of the distributer box, a spring I being interposed between the box and stud and tending normally to hold the distinguisher in its extreme right-hand position in the box. Inasmuch as the position of the distinguisher m should depend upon the extent of projection of the distinguisher x I provide means for effecting their corresponding adjustments. In the present instance, these means comprise a rocking lever J connected at one end to the stud I and at its opposite end to the casing H The lever J is fixed to one end of a rock shaft J journaled in suitable bearings in the framework and provided at its opposite end with a crank arm J 2 which is connected to a third upright lever J The three levers G J and H are arranged side by side in close order (Fig. 1), all being pivotally mounted at their upper ends upon a common stud K and having their lower ends arranged in position to be engaged by a pair of plates Gr and J connected to the side edge of a magazine. The plate G which controls the point-distinguisher m is of such shape and size, that when the magazine is brought into action, it will rock the lever G so as to cause the distinguisher, through the intermediate connections, to be set in a position corresponding to the notch X of the matrices contained in the magazine. The plate J (Fig. 1) which controls both face'distinguishers m and m is provided with two distinct surfaces J and H to engage the levers J and H respectively. The size of the plate or the shape of the two faces is such as to rock the two levers J and H the proper extent to locate their respective distinguishers in position to correspond to the location of the face'distinguishing notches X. X of the matrices in the magazine. It will be remembered in this connection that the lever J controls the horizontal adjustment of both the distinguishers m and 00 while the vertical adjustment of the former is controlled by the lever II.

It is to be noted that plates G and J are attached to each of the magazines and that their form or size are made to correspond to the particular font of matrices therein contained, both as regards point and face. For instance, the upper magazine in Fig. 3 is shown as provided with a plate G corresponding to a six-point font and a plate J" corresponding to an antique No. 4 face: while the lower magazine in this figure is shown as provided with a plate G corresponding to a twelve-point font and a plate J corresponding to an old style No. 2 face. Again. in Fig. 4 is illustrated a plate G corresponding to a six-point font and a plate J corresponding to an old style No. 1 face. The plates G and J are detachably connected to the magazines by screws L so that they may be replaced by others of different sizes or forms corresponding to other fonts. In this way each the magazine thus brought into action, yet I it will be understood that my invention is equally applicable to machines employing a single magazine, wherein the adjustment of the font-distinguishers will be controlled by the substitution of a magazine in that type of machine. ()r, as before stated. the adjustment of the font-distinguishers may be effected manually. It will also be understood that the particular embodiment of my invention as herein shown is merely by way of example and may be widely varied by the skilled mechanic without departing from its scope. It will be obvious, of course, that the notches X and X of the matrices might also be used to distinguish fonts of unlike point instead of face, the invention in its broad aspect including all combinations or uses of such notches as are defined by the claims.
